Inventor: SUMIDA TADASHI
IPC: E03C1/28
Filed: 1994-12-15
Abstract: PURPOSE: To facilitate the positioning of a hole core for a drain trap with the hole core of a drain hole for a bathroom floor pan. CONSTITUTION: The execution structure is equipped with a suspended frame 2 mounted between the foundations 3 of a building, and with a trap receive fitting 12. A drain trap is supported by the trap receive fitting 12 in such a way as to be slidably in the horizontal direction A so that the drain trap can be moved with respect to the drain hole of a bothroom floor pan.

IPC: H05B41/16
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To stop lighting of a discharge lamp upon detection of the occurrence of discharge in a circuit between a booster circuit and the discharge lamp. SOLUTION: DC voltage from DC current 10 is converted to preset DC power via a power control circuit 12, and DC voltage available therefrom is boosted with a booster circuit 14 for lighting an discharge lamp 24. When discharge takes place between the booster circuit 14 and the discharge lamp 24 and the voltage of the booster circuit 14 becomes high, the rise of the voltage is detected with voltage divider resistors 16 and 18. A low level signal is outputted from a comparator 32 to an AND gate when detected voltage exceeds discharge judgement reference voltage 34, thereby stopping power conversion control of the power control circuit 12.
